There is a far-reaching “peace obligation”, i.e. a duty on the part of the trade union which is party to a collective agreement, and often also its members (the individual workers), not to take industrial action (strike, lock-out, blockade, etc.), when a collective agreement is in force.
Existe una amplia "obligación de mantener la paz", es decir, el deber por parte del sindicato que sea parte en un convenio colectivo, y a menudo de sus afiliados (los trabajadores individuales), de no realizar acciones reivindicativas (huelga, cierre patronal, bloqueo, etc.) cuando está en vigor un convenio colectivo.
